I"m using Flex 4 and an AdvancedDataGrid. I need to keep track of the previously selected item. I can't think of where to capture this though. In an itemClickHandler method, the grid's selectedItem value is already the current selected item.

Here's the situation: I have a populated datagrid and I want to move a form to be inline (same y position) with the datagrid's selectedItem. I cannot rely on a mouseClick event because the selected item may change with a keyboard event. The datagrid does not have an itemRenderer, just plain old dataField.Anyone done this before?
Here's some stubbed out example code for all those interested based on Jacob's answer.

I used HTTPService POST method to call a php file that returns me an xml type of result like
<user>
<name>jones</name>
<age>34</age>
</user>
This result is obtained after the php files queries a database. The database contain other information too like (height, gender, education and address)Now i have a DataGrid (having two columns: NAME and AGE) and a Form below the DataGrid. I have displayed the above mentioned xml data in the DataGrid using the dataprovider="{userRequest.lastResult.User}" attribute.
I now want to use the itemclick=itemClickEvent(event) so that when a user click on a row of the DataGrid other information related to the clicked row like (height, gender, education etc) may appear in the form which is placed below the DataGrid in the GUI. For now my itemClickEvent, look like:
private function itemClickEvent(event:ListEvent):void
{
clickRow.text=String(event.rowIndex);
//Don't know what should i assign to following labels...
[code]....
I need to get the value of the item clicked and the name of the columns.[code]But this way it returns 'undefined'.But if I put the name already in function, I can get the correct data, example:Alert.show(''+datagridlist.selectedItem.create); // create is a column name in mysql.But this variable must be created dynamically, example:[code]I'm at it on time and I can not convert the string to column name.
View 2 Repliesi am working in Air application in Flex3 , i need know how to set "selectedItem" Property when we have 2 values like(data and label) label property to combobox selection, data value for our input.In (selectedItem="{stylename}") stylename will have "data" value but i need to set that "lable" property as selected value in combobox.Like if stylename is "checked" then the ComboBox selected item need to be "Checked".How to implement this in flex.
View 1 RepliesI am making some simple project and I have problem with selectedItem. I have sth like this
<s:State name="Form" enterState="makesService.send()"/>
so when I enter this state I take makes from database and populate them to dropdownlist.
but I have also button and on click event I'm changing state to this Form and I want to select specific make from the dropdownlist but I can't. I'm not sure whether I'm doing sth wrong or the problem is that I'm selecting item just before the dropdownlist became populated.
e.x. List of make consist of Audi and BMW and when I click button I want to open this state Form in which this dropdownlist exist with selected value e.x. BMW.
I've got a combobox, cb, for which I need to programmatically set the selection. The combobox was populated by:
cd.addItem({data:"string1",label:"string1"});
cd.addItem({data:"string2",label:"string2"});
cd.addItem({data:"string3",label:"string3"});
Lets say I need to set the combobox to "string2",I've tried all of the following, none work:
cb.selectedItem("string2");
cb.selectedItem(data:"string2");
cb.selectedItem(label:"string2");
cb.selectedItem({data:"string2",label:"string2"});
The docs say selectedItem() is read/write but all the examples I can find are read only.
I am creating a lot of dynamic flex components like RadioButton, Combo Box, CheckBox.
[Code]....
When i click on Submit finally i need to get all the selected Values in each question. All the components are dynamically created at runtime.
Does anyone know how to change the myComboBox.selectedItem or at least make it act as if it were changed (meaning on the screen it remains the same, but i can refer to the myComboBox.selectedItem property later on with actionscript and use it.The selectedItem property is inherited from the List class.
Basically what I'm trying to do is build a media player, and I have my playlist in a combo box. The user clicks on a song to start it. Then when that song finishes, the onSoundComplete method is called from the Sound class, and it will move to the next item on the combo box and start playing that song.Btw, as in the title, I'm using UI components 2, actionscript 2.
When I change the: list.selectedItem.name = 'name2'
then in my item renderer
the dataChange event is not fired! and I can't update the label with the name property...

View 1 RepliesI have encountered somthing a little strange in flex, possibly somthing im doing wrong but im not sure. In two cases which i have noticed, when there is only 1 item in a s:List or s:DropDownList for some reason when using list.selectedItem it appears as null. Using requireSelection="true"i know this isnt the case.

I have a list box of mp3s which populates via xml. When the user clicks on a song I want a "Stop" button to pop up next to the name of that song in the list box. Ideally I want to get the coordinates of the field in the list box that the user has just clicked on.

Ok I can't find any doco on this and it's driving me crazy. Anyone know how you specify the default value for the V2 ComboBox component based on the selectedItem when you don't know the selectedIndex? Here's my scenario:
I have a hardcoded combobox called "dd_names" with 50 names in it. I'm returning a dataset into Flash via a SQL query, and onload I need the dd_names dropdown to default to the value of the name returned in the dataset. So if the query returns "Tom" I need the dropdown to default to "Tom."
I tried setting dd_names.selectedItem = "Tom" and dd_names.value = "Tom" and these don't work. The ComboBox just defaults to the first item in the list.However, if I use the selectedIndex property and set dd_names.selectedIndex = 3, the ComboxBox doesn't default to the first item in the list but shows the appropriate item. This doesn't help because I don't know the selectedIndex being returned from the query - I only know the selectedItem. Anyone know how to do this??
i have online game and i have to know how to do this easy thing i have inventory and under things like first aid is number of objects and its combobox and after change i want to change variable kolko[i] to equals combobox name : "co"+i and that selecteditem data , i have this
[Code]...
well, I have a combobox which I have bind his selectedItem property to a value object object, like this
<fx:Binding source="styles_cb.selectedItem.toString()" destination="_uniform.style"/>
<fx:Declarations>
<fx:XML id="config_xml" xmlns="" source="config.xml" />
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<mx:ComboBox x="66.15" y="63.85" editable="false" id="styles_cb" dataProvider="{config_xml.styles.style}" />
the value object is a custom class with some setters and getters, and I want to set a property based of the value of the selectedItem of the combo, so inside the value object I have something like this
[Bindable]
public function set style(value:String):void
{
_style = value;
trace(value);
}
my problem is that each time I change the combobox selection which in fact change the style property of the value object it does it 3 times, if I trace the value of the setter it actually do the trace 3 times, why?? how can I avoid this? I'm doing something wrong? or there is a better way to do it,

When I move page01 to page02, I pass the same data along with it using the following code:navigator.pushView(Page02, data);How do I move to page02 with passing the next row of data (instead of the same data)? In other word, how to increment to the next row of data with pushView?

I have a tabbed view with in the second tab a splitview controller.
The master view shows a list. When selecting an item from that list it opens a second view with a new list by using navigator.pushView.
When I select an item in the second view/list it has to be passed to the detailview. Is there a simple solution available?

I have a datagrid with some custom renderrers and I'm just curious how I should approach the ability to freeze and always show the left 3 most columns at all times when scrolling left/right.
I thought that I might have to resort to 2 datagrids, side-by-side, the first showing the 3 columns that I want at all times, and the ability to scroll the rest. Only issue then I guess is linking the row selection to select that row in both and to tie the column sorts together...
Or would it be better to try and take columns 4+ and shrink their width to 0 as a person scrolls right, and then increase it back to the max width as they scroll left? Though that would cause funny issues to happen as the content of the datagrid would get smaller and smaller until you were 100% to the right and the scrollbar would disappear.
I've added an eventListener to the COLLECTION_CHANGE event that is fired when the grid is finished resorting the items in its dataProvider, after the user clicks on a column header:MyType (myDataGrid.dataProvider).addEventListener(CollectionEvent.COLLECTION_CHANGE,onDataGridResort);
View 1 RepliesI am working on a problem since a week soon, but I still couldn't make it work as expected. I have a DataGrid which has HBox with a CheckBox an a Label as itemRenderer (see Code below). When I tap in to the Cell the standard itemEditor pops up and lets you enter the content of the label. Thats the standard behavior. I works fine except for 2 problems:
If I enter to much text, the horizontal srollbar pops up, and the cell is filled with that scrollbar. As you see I tried to set the horizontalScrollPolicy to off, but that doesnt work at all... I tried to do that for all the different elements, but the failure is still existent. When I have filled more than one row, there is an other mistake happening. If I tap on a row, the datagrid selects the one below that row. That's only if one line is already selected. If I tap outside the datagrid and then, tap at any row the itemEditor of the right row will show up... Is there anything now wright in the setup of my set data method?

From this (normal dataGrid)
into this (horisontal data grid)
How to turn Flex MXML DataGrid into something like Horisontal DataGrid? (may be some how with Flash builder 4?)
Keeping all stuff DataGrid has like eating data from data provider sortind dragging - droping items etc
I have two datagrids:
- Division
- Members
Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.
[Code]..
For poor performance reasons, the DataGrid will cache checkboxes and reuse them for different rows. If you have 50 rows, it won't create 50 checkboxes. It will create as many checkboxes at are visible, plus a few more for padding, and then reuse them as you scroll. This is why you need to explicitly manage their state. How can improve it ? How can fixed checkbox value ? i used checkbox like below But checkbox doesnot remembering the values
